Chapter 6: Contradictory Pairs

Show Summary Details


This chapter, which concludes the introductory section of the work, narrows the focus to simple assertions. Aristotle demonstrates with brilliant neatness that all such assertions either affirm or deny, and that moreover they may be ordered into pairs, one representing a pair of simple elements as combined, the other as separated. His approach reflects his ’internal’ theory of negation: very different from the Stoic ’external’ view more familiar to later logicians. His definition of negation does not presuppose anything about the truth or falsehood of the two members of a contradictory pair.
